Use AES Encrypt to Encrypt EID0 Key Seed as data with EID Root Key as Key and EID Root IV as IV. The result contains from 0x10 to 0x20 the EID0IV and contains from 0x20 to 0x40 the EID0Key

Correct would be 0x10-0x1F EID0IV and 0x20-0x3F is EID0Key.

And:

Build the CMAC (OMAC1) hash of the decrypted EID0 Section from 0x00 to 0xA8 with EID0 First Section Key as Key. The calculated hash has to be the same as the bytes in the decrypted EID0 Section from 0xA8 to 0xB8.

0x00-0xA7 and hash is in 0xA8-0xB7

I did it, it works great. If you willing to try yourself, I suggest to download this flashCEX.7z/flashDEX.7z from first page and try to get the same encrypted eid0 from cex as in flashDEX.7z
